SASH=FASTENER.

SPECIFICATION forming part of Letters Patent No. 356,182, dated January18, 1887.

- Application iilrd July 3, 1856. Serial No. 07,090. (Model.)

To all whom t may concern:

Be it known that we, J oI-IN Wnrrn'and GUs THoMils, citizens of theUnited States of America, residing at Fulton, in the county of Obion andState of Tennessee, have invented certain new and useful Improvements ina Vindow or Sash Lock, of which the following is a pivoted above thecenter to a seat secured on` the window-sash in such .a manner that thelower end will hang perpendicularly from the pivot, while the upper endprotrudes forward, so as to engage with stationary studs arranged in thewindow-frame- It also consists in the inode of mounting such fastener sothat the lower end will hang vertically from the pivot along close tothe windowsash, while the upper end protrudes forward sufficient toengage with the stop studs.

it also consists in providing said fastenerwith catching-lugs at eachend, and, when V.desired, with double lugs at the upper end,to preventthe window Vfrom being accidentally displaced; also, in the manner ofsecuring such fastener to the windowsash and engaging it with thestopstuds, also, in the mode of operating the same.

Figure lis an open window, shoi'ving the fastener on the lower sash, aswell as the engaging stop-studs in the window-frame. Fig. 2 is avertical cross-section of the saine, taken at the dotted lines a: a,showing the fastener engaged. Fig. 3 is a fragment of the edge of thewindow-sash, showing the fastener enlarged, being an edge elevation.Fig. 4 is another fragment of a window-sash, showing the fastener indetail, being a plan view of the same. Fig. 5 is another fragment of awindow-sash, showing a modified form of the fastenerin detail, beingalso a plan view.

Similar letters of reference indicate corresponding parts.

A is awindow-frame. B B are window-sash. a is a window-fastener, pivotedat c. is a metal seat, secured to the window-sash B by screws b l), towhich the fastener is pivoted;

and d d d and g are stop-studs set in the side of the window-frame A,with which the window-fastener a engages to secure thewindow in place.

The metal fastening-bar c, which need not exceed threeinches in length,a quarter of an inch to th rce-eighths in width, and a sixteenth to aneighth of an inch in thickness, assumes in form an obtuse angle, thepivotal center c being the corner. At each end of the fasteningbar a, onopposite edges, is a truncated lug or catch, n o, preferably slightlyhooked for engaging with the stop-studs d d g, to fasten the window openor closed, respectively. For the purpose ofsafety we prefer to use twolugs, n u, on the upper end ofthe fastening-bar c, as seen in Fig. 5.

rilielo wer portion offastening-bar c is longer and heavier than theupper portion, so that when pivoted in its seat the lower portion willpend vertically close along the sash, thereby thrusting the upper andshorter portion forward to engage with the stop-studs d to keep thewindow open.

Anything to which the fastener a can be pivoted that may be fastened tothe window-sash will serve as the seat i for the fastening-bar a,provided it is permitted to move freely.

The studs d d d are introduced at suitable intervals into .thewindow-stops by the side of and at a suitable distance from the sash toallow the catch-lug n on the upper end of the fasteningbar a to engagenaturally therewith. The stud gis introduced lower down in thewindow-stop, close to the sash, in such a position that when the windowis closed the lug o on the lower end of the fastening-bar a willnaturally engage with it and fasten the window closed.

It will be observed that the fastening-bar a able mischief is by thisdevice and mode of fastening windows wholly overcome, and so, too, isthe danger of leaving the Windows uufastened through carelessness or byaccident, as this fastener works automatically. The Window cannot beclosed Without being` fastened, unless through design.

Having new fully described our invention, what we esteem as new, andseek to secure by Letters Patent, is-

l. A pcudulous elbow-shaped double latch in one piece having; a pivotalpoint above the center, and Whose opposite arms form an obtuse angle tocach other from the pivotal point and are provided with catches neartheir ends on opposite edges, and adapted to go over catches for thepurpose ol' locking, substantially as shown and described.
